A guy over on eBay sells all sorts of track mountings and I noticed that he had some that would work on my Native Propel 10. The photo shows a Harken 29C on the track. There is one at the front of port track in the cockpit . . . about where my left foot would be, then I have another at the farthest back track point on the stern, then a track mounted Zig Zag cleat.
